Answer:
d. to protect the end of a DNA molecule
Explanation:
Telomeres are like the protective shields of our cells' DNA.
Its name, of Greek origin, literally means "final part", and the telomeres are that: the ends of the chromosomes, something similar to the plastic tips of the shoelaces.
But they are very repetitive and non-coding parts of DNA: their main function is to protect the genetic material that carries the rest of the chromosome.
As our cells divide to multiply and to regenerate the tissues and organs of our body the telomere length is reduced, and so over time they become shorter.
When the telomeres finally remain so small that they can no longer protect the DNA, the cells stop reproducing: they reach a state of old age or old age.
Therefore, telomere length is considered a key "biomarker of aging" at the molecular level, although it is not the only one, and in recent years it has attracted the attention of numerous investigations.
Answer:
Brainliest pls
Explanation:
That's because transcription happens in the nucleus of human cells, while translation happens in the cytosol. Also, in eukaryotes, RNA molecules need to go through special processing steps before translation.
Answer: it’s a producer
Explanation: The grass is a producer because it produces food while other animals get food themselves.
True because it makes since and it’s a better answer than false
Homozygous recessive: tt
Heterozygous: Tt
Cross:
t t
T Tt Tt
t tt tt
Thus, the expected outcome genotypic ratio is:
1 Tt : 1 tt
