Answer: the name used is polytene chromosomes.
Explanation:
Polytene chromosomes are produced when repeated rounds of deoxyribonucleic acid (DNA) replication without cell division forms a giant chromosome, they have thousand of DNA strands and provides high level of function in the salivary glands.
At interphase, polytene chromosomes are seen to have distinct thick and thin banding patterns, these bands are of 2 types, the dark band (dark stained,
contains more DNA and less RNA) and the interband (light stained, more RNA and less DNA). The bands enlarge and forms a swelling called puff in certain times, the puffing (which is the formation of puff) is caused by the uncoiling of individual chromomeres in a band. The puffs indicate the site of active genes where mRNA synthesis takes place. These distinct banding patterns are used to study the function of genes in transcription because they permit high level of gene expression.
Answer: Bb
Explanation: a heterozygous genotype will always result in the dominant phenotype
Answer:
True
Explanation:
Conditions such as temperature and pH are critical for biological molecules and should be well maintained. If the pH changes in an abnormal manner then the structure of the biological molecules might change and they will not be able to perform their functions. For example, the amino acid side chains can be disturbed due to pH changes which result in the unfolding of the protein or the protein structure to get changed, As a result, the protein will not be able to carry out its function. Hence, the statement is true.
