Answer:

substitution - a base was changed

Explanation:

The nucleotide sequence CTT was changed to the sequence CAT. The T was substituted with an A. This changed the encoded amino acid from Glu to Val.

An insertion is where an additional base is added (e.g. if the sequence changed from CTT to CATT)

A deletion is when a base is lost (e.g. if the sequence changed from CTT to CT)

What one trait do only plants, algae and Cyanobacteria have in common?
bogdanovich [222]
Cyanobacteria are oxygenic photosynthetic bacteria. They harvest the sun's energy, absorb carbon dioxide, and emit oxygen. Like plants and algae, cyanobacteria contain chlorophyll and convert carbon dioxide to sugar through carbon fixation. Unlike eukaryotic plants and algae, cyanobacteria are prokaryotic organisms.

In eukaryotes, how can a single gene code for several different proteins?
NikAS [45]

Answer:

Gene splicing is a post-transcriptional modification in which a single gene can code for multiple proteins. Gene Splicing is done in eukaryotes, prior to mRNA translation, by the differential inclusion or exclusion of regions of pre-mRNA. Gene splicing is an important source of protein diversity.

A species of mud snail was studied for five years. During this time, scientists observed the season in which they mated, the num
sergij07 [2.7K]

The correct answer is option B. The scientists were studying if the mud snails can reproduce both sexually and asexually. The characteristics in the study included parameters such as the mating season, number of offspring, effect of environmental stress conditions and lack of mates. Out of all the parameters being studied can affect asexual reproduction in the mud snail but lack or presence of mates is a parameter required to be studied to determine the mode of reproduction i.e. sexual or asexual because need for mates or mate dependent reproduction occurs in case of sexual reproduction.
